CARRIAGE-RETURN ATTACHMENT FOR TYPE-'WRITING MACHINES.

. Be it known that we, RALPH-Wam Les@ WoRTHY and lHOMER HAMILTON SAVAGE, c1t1- zens ofthe United States, ad residents of county of Pima and State of Arizona,1 and Phoenix, in the -county of .MaI-impe, State of Arizona, have invented' certain new and useful Improvements in Carriaglteturn Attachments for Type-Wr1t in achines; and we do hereby declare the :Eo lowing to be a full, clear, and exact deu scriptio'n of the invention, such as wiil enable thers skilled in the art to which it apperta`ns to make and use the same.

This invention relates to improvements in typewriting machines, land more particuto means for returnn the carriagefthe object of the invention a simple and eiicient mechanism which may be quicklyv and securely attached to the. frame 'of a typewriting machine and which the knee 'of the o erator, in leiecting thev return of thecar- 'th-t inventionconsists in certain features of cnstruction and combinations of arts as here-4 "Inaterl set forth and point y plams.

3 and is providedv with a Shaft or arbor 9 mounted m two plates of said frame. n arm 10 is also attached to the frame 3 and projects therefrom -in an inclined direction and is of suchllength that a pulle 11 car- 60 ried by said atm near its free. en w-ill be disposed approximately in horizontal alinement with the line space riage of the machine. A wire 13 (or other flexible device) is woundl the grooved Wheel 8 and extends therefrom over the pulley 11 at one end of the arm 10, and at its other end, said wire is attached to the line space lever'12. The arm 10 may conveniently consist oi self to form two parallel memberspivotally connected with two of the plates of the frame provided with a plurality of holes 14, any

one-of which may receive a pin 15 on one of '75 the. members of the arm 10, whereby said arm may be held at any oneof severala'dattachment tov h typewriting machines of different-sizes and stand other objects in view the 1 y an arbor 18 mounted in the frame' 3. -The arbor 18 also carries a pinion 19 and motion 85 is im mounted in the lower portion of th'e framework. The shaft. 21 is providedwith a deor bowed somewhat as shown in Fig. 1, and

lever 12 on the caron and attached to a rod bent upon it- 3. One of the frame' 'plates maybe parted to the same by means of a toothed segment 20 secured to ashaft-Zl,-

' pending lever 22 which is l'preferably curved V90 'l is ofsueh length and so positioned as to be disposed in proximity to the knee of theperator.

i It Awill be apparent that' a 'limited side 95I movement of 'the knee -of the operator against the' lever '22, will cause motion to be vimpar-ted-.-throngh the .gearing a scribed, to Vthe grooved wheel 8, sothatsaid wheel willbe turned and cause the Wirej cient pull lon also return ,the carriage' of space lever and t bove de` e/typewriting machine to its starting,pci'si-I l `tion.l

4a pinion carried by said wheel, a depending lever mounted in said frame,

and gearbetween said lever and the wheel, of an arm pivoted at one end to said frame. and projecting latering interposed 4ally therefrom, a pulley mounted near the lsaid frame, a pulley carried 2. A carriage return Writing machines, comprising a frame, a Wheel limoun.t ed therein,

by said arm, a flexibledevice for attachment to the carria e of the machine, said flexible device attac 'ed to the wheel and passing over said pulley, a pinion connected with said wheel, an arbor mounted inthe frame, a segment carried by said arbor and meshing with said pinion, a pinion carried by said arbor, an operating shaft, a' segment carried by said'operatin shaft and meshing with the last-mentione pinion, and an operating lever carried by said operating shat.

In testimony whereof, we have signed this specification in the presence of two subscribing witnesses.
